Bootloop

A bootloop is a problem that occurs on computing devices which are unable to complete the regular booting sequence and reboot before it is finished.

I ran into this while configuring my Jetson, when I upgraded from Jetpack 5.1.1 to Jetpack 5.1.2 at NVIDIA.

How to fix bootloop?

Sucks to suck, but I believe you have to reflash? Or you can go into the boot manager and try to fix it.
